Hi @go-to-k quick question, why does it use npm?
I'm new to AWS CDK

npm install image-scanner-with-trivy

[go-to-k]

Hi, @AnaisUrlichs.

AWS CDK has a feature called "Construct" that allows users to freely define resources, which can then be uploaded to a platform called "Construct Hub" as Construct libraries. The "image-scanner-with-trivy" I created this time is one such example.

"Construct Hub" is simply a collection and listing of Construct library packages that have been published to the npm registry.

In other words, these Construct libraries are actually npm packages, so if you want to use them with AWS CDK, you will need to install them via npm separately from the CDK CLI, so use npm.

You can also use yarn and so on.

Ah, thank you for clarifying
